Through August 31, Hyatt is offering free Platinum status for 120 days for new account signups, and a fast track to Diamond: 5 Hyatt nights within the promo period retains Platinum and 15 nights achieves Diamond.

With the huge improvements that Hyatt announced in April — especially the confirmed suite upgrades for Diamond members — Gold Passport may offer the best elite program currently making this a good time to consider switching to Hyatt.

And while you work on the Diamond fast track you can also earn 2500 bonus points per stay (through September 15).

Hat tip to One Mile at a Time. And as lucky points out, you could wait closer to the end of the promo period to sign up and possibly overlap with Hyatt’s standard Faster Free Nights offer which may come next quarter (two one night stays earn a free night).
